18 Claims. 1

The present invention relates to fastening devices for anchoring carpets to floors and the like.

An object of the invention is to provide preformed anchoring strips for securing a carpet to a floor, which are capable of properly locating the carpet with respect toan adjacent wall, and which avoid the exposure of raw carpet edges.

Another object of the invention is to provide preformed anchoring strips for securing a carpet to a floor, in which the marginal edge of the carpet is readily guided into the interior of the strips.

A further object of the invention is to provide a generally channel-shaped anchoring strip provided with a guide for insuring proper and easy insertion of. the carpet into the strip, in which the guide properly locates the marginal portion of the carpet adjacent the wall of the room.

Yet another object of the invention is to provide carpet anchoring strips capable of clamping about the marginal portions of carpets to prevent unraveling of their threads, such as the catcher threads of chenille rugs or carpeting.

Another object of the invention is to provide comparatively rigid carpeting anchoring strips capable of being nailed to floor at widely spaced points without danger of flexing of the strips between the points at which they are anchored to the floor. Accordingly, installation of the strips is faster, easier and more economical.

A further object of the invention is to provide carpet anchoring strips that can be removed from the floor without damage, enabling them to be re-used, if desired.

This invention possesses many other advantages, and has other objects which may be made more clearly apparent from a consideration of several forms in which it may be embodied. Such forms are shown in the drawings accompanying and forming part of the present specification. These forms will now be described in detail, illustrating the general principles of the invention; but it is to be understood that such detailed description is not to be taken in a limiting sense, since the scope of the invention is best defined by theappended claims.

Referring to the drawings:

Fig. 2 is a top plan view of a plurality of carpet anchoring strip members joined together;

Fig. 3 is a top plan view-of a carpet anchoring memberfor use at a corner of a rooms Fig. 4 is a cross-section through a carpet anchoring strip, rug and room;

Fig. 5 is a cross-section, similar to Fig. 4, disclosing a modified form of carpet anchoring strip, in an initial position;

Fig.6 is a view similar to Fig. 5, disclosing the carpet anchoring strip in its final position securing the carpet in place;

Fig. 7 is a cross-section disclosing another form of carpet anchoring strip installed in a room;

Fig. 8 is an isometric view, partly in section, disclosing another embodiment of carpet anchoring strip.

In the form of invention shown in Figs. 1 to 4,

inclusive, a carpet anchoring strip I0 is preformed to provide a generally channel or U-shaped crosssection. The interior of the channel member is adapted to receive the marginal portion of a carpet or rug C.

The channel shaped carpet strip [0 may be made of any convenient length and of any suitable material, such as light gauge sheet metal. The channel member includes a bottom flange H having an outer, upwardly directed, inclined spacer and guide portion l2 adapted to be-disposed against a wall or wall base W. The top flange I3 of the channel terminates inwardly of the outer edge M of the inclined guide, and may be disposed substantially parallel to the bottom flange II by the interconnecting web or base l5 of'the channel member itself. If desired, the outer margin of the top flange l3 may be folded upon itself to provide a rounded edge [6.

At spaced intervals along its length, thetop flange I3 is notched, or cut out, to form openings I1 through which a hammer (not shown) can operate to drive nails 13, inserted through holes 19 in the bottom flange I I, into the floor F of the room. The bottom flange nail holes I9 and the top flange openings ll thereabove may be placed at suitable-intervals along the length of the strip. As disclosed in thedrawings, they are provided at the ends of the strip. One end of the strip HI may constitute a female portion 2i] and the end 2| of an adjacent strip 22 may be reduced in size forinsertion into the femaleportion 20, thereby assembling the stripmembers together to provide the desired length along the floor. The opening IT in the top flanges I3 of the adjoining male and female ends 26, El combine to provide a single opening through which a hammer head can be readily manipulated, the nail holes [9 in each strip end overlapping and being in alignment with one another.

For the purpose .of attaching the'carpet C to the strip and prevent its inadvertent removal, a plurality of anchoring teeth or pins 23 project upwardly from the top flange I3. These pins are inclined in a direction toward the rounded edge I6 of the top flange, and may be formed by punching them upwardly from the top flange, or the teeth 23 may be separately formed and secured, as by welding, to the top flange,

The strip I0, formed of as many sections as are required, is placed upon the floor F, with the spacer guide I2 abutting the wall W of the room. The nails I8 are then inserted through the openings II and aligned holes I9 and are driven into place by the head of a hammer. In this manner, the strip is firmly secured to the floor. A rug pad P is then placed upon the floor, with its edge abutting the web portion I of the channel strips. Ordinarily, the pad is of the same height as the web.

The rug or carpet is then placed upon the pad P and its marginal portions inserted through the space 24 between the rounded edge I6 of the top flange and the wall W. This portion is guided into the channel by the inclined spacer portion I2 of the bottom flange II. The marginal carpet edge can be fed into the channel, its reverse movement being prevented by the embedding of the anchoring pins 23 into the carpet material. In view of the fact that these pins 23 are inclined toward the wall, the slack can be taken up in the carpet merely by pressing it toward the wall, the carpet material riding 01f the pins, and then being gripped by the pins when the carpet tends to shift in a reverse direction.

A corner member 25 is disclosed in Fig. 3. This member is made in exactly the same manner as the carpet strips I0 heretofore described, except that adjacent strip portions have beveled or mitered corners 26 abutting one another, which can be suitably attached to one another. Each beveled portion may be secured to the floor F to hold the mitered corners in abutment, or the corners themselves may be attached to one another, as by welding.

In the form of invention disclosed in Fig. 7, the carpet anchoring strip I0a may be secured to a concrete floor G by being anchored directly thereto upon pouring of the floor. Thus, the bottom flange Ila is provided with a sheet metal angle strip 21 suitably secured thereto, as by use of welding material 28. The top portion 29 of the strip is attached to the lower surface of the bottom flange Ila, while the depending leg 30 of the strip 21 is disposed downwardly and is inclined away from the plane of the wall W.

The strip Ina is properly supported, with its inclined spacer and guide I2a abutting the wall, and the concrete floor G is then poured under the strip and around the flange 30. When the concrete hardens, the flange portion 30 is firmly anchored to the concrete, and thereby prevents the strip Illa from being removed from the concrete floor.

The carpet C may be inserted in the strip I0, and the teeth 23a of the strip anchored to the carpet, in the same manner as was disclosed in the other form of the invention.

It is apparent that the inclined spacer and guide I2 serves to space the outer edge I6 of the top flange a proper distance from the wall, allowing suificient room 24 for insertion of the carpet into the channel shaped member. In addition, it serves as a guide for feeding the carpet readily into the channel without difliculty.

Each carpet anchoring strip section III can be 4 made of any suitable length. For example, it could be made in two-foot lengths, which may be carried and handled conveniently. The

lengths, as described above, are joined together to provide a strip of the desired extent. If longer lengths are used, the holes I9 and the openings II in the bottom and top flanges II, I3 would be provided at intermediate points along the strip. Although the strip is made of sheet metal which can be relatively thin, its preforming'into a channel shape makes the entire structure comparatively rigid and requires that the strip be nailed, or otherwise secured, to the floor at comparatively widely spaced intervals. As an example, the spacing of the nails two or three feet apart is suflicient to hold the entire strip structure firmly anchored to the floor F and properly re-' lated to the wall W of the room. Such wide spac ing enables the installation to be made in a more rapid, easier and economical manner. As shown in Fig. 2, it is only necessary to couple the sections to one another and drive nails I8 through the sections into the floor at each strip joint 20, 2 I.

In view of the fact that the marginal portion of the carpet C is turned under and into the strip, no raw edges are exposed. The carpet is laid substantially flush against the wall W in a smooth and attractive manner. I

In the event that the carpet is to be removed from the floor, it need merely be stretched toward the wall to slide it off the anchoring pins 23. The carpet can then be withdrawn from the anchoring strip III. The anchoring strip can also be removed merely by pulling the nails I8 from the floor, without damaging the strip itself. This enables the strip to be re-used at the same or another location.

In the form of invention disclosed in Figs. 5 and 6, av carpet anchoring strip Illb is provided for clamping the marginal portion of the carpet or rug C and for preventing unraveling of its threads. This strip is of essentially the same channel shape as the other anchoring strip I0, but is initially formed with the top and bottom flanges I3b, I lb making an obtuse angle relative to one another; so as to provide a. relatively wide opening at its outer portion. The top flange I3b has inclined teeth 231), as in the other form of the device, and it is also bent or folded upon itself at an intermediate portion to form a downwardly extending longitudinal rib 35. In a similar manner, the lower flange has a bend or reverse fold 36 to provide an upwardly projecting longitudinally extending rib which is out of alignment with the upper rib 35. As disclosed in the drawings, the lower rib 36 is disposed forwardly of the upper rib 35 by a certain distance.

The strip Illb is disposed across the floor F and is secured in place by the nails I811. The carpeting C, which may be chenille, possessing catcher threads T that tend to unravel, is then inserted around the upper edge I612 of the flange I3b and into the channel member. Thereafter, the top flange I3b is bent downwardly toward the bottom flange III). This causes the ribs 35, 36 to approach and overlap one another, in order to clamp the marginal portion of the carpet between the ribs, and also between the ribs and the flanges IIb, I3b opposite the respective ribs. The location of the ribs 35, 36 and the extent of their projection into the channel space is determined so that a substantial clamping force can be exerted upon the threads of the carpet. This force is of such an extent as to prevent pulling catcher threads T.

When the top flange H2) is swung downwardly toward the bottom flange llb, firmclamping of the carpet to the channel IDb is assured, when the top flange is parallel to the bottom flange and the floor. This arrangement insures the disposition of the carpet along a flat, horizontal surface.

In all other respects, the channel strip disclosed in Figs. 5 and 6 is essentially the same as the channel strips disclosed in Figs. 1' to 4," inelusive, and Fig. 7.

An anchoring strip for use across thresholds; or in areas where no wall is present, is disclosed in Fig. 8. This anchoring strip 40 is of generally angled or L shaped section, the top flange 4| ot the strip having its outer edge 42 exposed, with the inner portion of the flange merging into .a downwardly extending vertical Web 42a which engages the floor F and positions the top flange 4| in inclined relation to the floor, so that there is no abrupt line of demarcation between the floor surface itself and the strip. The strip is secured to the floor by nails I80 and is provided with anchoring pins 23c inclined in a direction toward the outer margin 42 of the strip, to grip the rug in the same manner as in the other forms of the invention.

The strip All is secured to the floor across the doorway, or other opening, and the rug pad P placed on the floor F with its outer edge engaging the web 42a of the strip. The rug C is then placed over the pad, and its marginal edge E disposed over the strip so that the pins 230 embed themselves into the rug material. Ordinarily; at such exposed points the rug is provided with a suitable binding B.

Because of the inclination of the strip-into the floor, the marginal edge E of the rug is also given an inclination, to avoid any abrupt changes between the bare floor surface and the carpeted The inventor claims:
